12x3−(4x2×2)=0
Multiply the terms
12x3−8x2=0
Factor the expression
4x2(3x−2)=0
Divide both sides
x2(3x−2)=0
Separate the equation into 2 possible cases
x2=03x−2=0
The only way a power can be 0 is when the base equals 0
x=03x−2=0
Solve the equation
More Steps

Evaluate
3x−2=0
Move the constant to the right-hand side and change its sign
3x=0+2
Removing 0 doesn't change the value,so remove it from the expression
3x=2
Divide both sides
33x=32
Divide the numbers
x=32
x=0x=32
